Research on long-term colonization of goosander (Mergus merganser Linneaus, 1758) with reference to habitat availability
(Srpsko biološko društvo, Beograd, i dr., 2008)
This article presents data on long-term colonization of goosander in Western Serbia and Eastern Republic of Srpska (on five oligotrophic reservoirs formed by the Drina River) based on continuous counting since the first ...
Effect of camphor essential oil on rat cerebral cortex activity as manifested by fractal dimension changes
(Srpsko biološko društvo, Beograd, i dr., 2008)
The aim of our study was to investigate the effect of camphor essential oil on rat cerebral cortex activity by fractal analysis. Fractal dimension (FD) values of the parietal electrocortical activity were calculated before ...
Investigation of Dynamic Behavior of Brittle Solids by Discrete Systems
(Union University, Faculty of Construction Management, Belgrade, 2008)
With the remarkably rapid growth of computer capabilities and corresponding
advance of numerical algorithms as background, the landscape of the engineering and
scientific research is continually changing. In the pre-computer ...
Synthesis of BaTiO3 from a mechanically activated BaCO3-TiO2 system
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2008)
In this article the solid state reaction of BaTiO3 formation from a mechanically activated BaCO3-TiO2 system has been investigated. An equimolar mixture of BaCO3 and TiO2 powders was activated in a planetary ball mill in ...
Ordering effect of kinetic energy on dynamic deformation of brittle solids
(Elsevier, 2008)
The present study focuses on the plane strain problem of medium-to-high strain-rate loading of an idealized brittle material with random microstructure. The material is represented by an ensemble of “continuum particles” ...
A Note on Short-time Response of Two-dimensional Lattices during Dynamic Loading
(SAGE Publications, 2008)
The disordered 2D lattices are used extensively to study damage
evolution and fracture of inhomogeneous or multi-phase systems. The present note
addresses their initial elastic response during dynamic loading. Namely, a ...
Electrical Characterization and Impedance Response of Lanthanum Doped Barium Titanate Ceramics
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2008)
The dielectric permittivity and dissipation factor of La-doped and undoped BaTiO3 were investigated as a function of frequency and temperature. The impedance response was used to study the electrical properties of La-doped ...
Effect of powder synthesis method on BaTiO3 ceramics
(Processing and Application of Ceramics, 2008)
Barium titanate (BaTiO3) has been of practical interest for more than 60 years because of its attractive properties.
BaTiO3 can be prepared using different methods, which can have signifi cant infl uence on the structure ...
Activities of antioxidative enzymes during Chenopodium rubrum L. ontogenesis in vitro
(Srpsko biološko društvo, Beograd, i dr., 2008)
For the short-day plant Chenopodium rubrum, a 14 h/10 h photoperiod is inductive for flowering, while continuous light (CL) is noninductive. Plants of one group were grown continuously under ail inductive photoperiod, while ...
Koncentracija cinka u zemljištu šumskih ekosistema NP ’’FRUŠKA GORA’’ / ZINC CONCENTRATION IN THE SOIL AND PLANTS OF NP "FRUSKA GORA"
(Šumarski fakultet u Banjoj Luci, 2008)
Da bi se uspostavio sklad između čoveka i životne sredine potrebno je dati pouzdanu i istinitu dijagnozu stanja i otkriti uzroke koji dovode do veće ugroženosti prirode. Ova konstatacija rađa cilj ovog rada, koji je najviše ...
